“Back by popular demand” is mostly a meaningless marketing term. The “popular demand” often isn’t all that widespread. However, this is an instance where the phrase might genuinely apply.
Wendy’s is conditionally bringing back its Spicy Chicken Nuggets, which almost certainly means they’re en route to your mouth. The popular nugs were unceremoniously pulled from the menu in early 2017. On May 4, Chance the Rapper tweeted about wanting to get those spicy chicken pieces back at this local Wendy’s. “Positive Affirmations for today,” he wrote, “I WILL have a good day, I Will succeed today, Wendy’s WILL bring back spicy nuggets at some point please please Lord let it be today.”
